Emerging Issues in Tropical Ecohydrology; June 5-9, 2016; Cuenca, Ecuador

热带景观约占全球陆地面积的五分之一，产生了地球上大部分的河流，并影响着全球和区域气候。此外，由于气候变化和森林砍伐，热带景观正在经历快速变化。在一系列尺度上，这些变化对水和生物地球化学过程的影响很大，但人们知之甚少。这次查普曼会议将审查目前对热带生态水文学的理解，并确定热带系统的关键研究需求。这次关于“热带生态水文学新问题”的查普曼会议将在厄瓜多尔的Ceunca举行，为期三天的会议和一天的实地工作。主题将包括：(1)生态系统退化和恢复的影响；(2)植物生态生理响应与流域水文联系的生态水文方法与技术；(3)跨尺度、跨生物群系水平衡机理评价新概念（如分布式模型）；(4)测量植物和河流水通量的新技术（如稳定同位素、树木年代学、sapflow、遥感、涡旋相关、分布式模型）；(5)建立生态生理学家和生态水文学家之间明确联系的方法。这次会议将产生一组综合论文，列出热带生态水文研究的关键问题，并为解决最紧迫的生态水文研究需求制定一个有凝聚力的战略。

Tropical landscapes account for about one-fifth of the global land mass, produce most of the Earth's streamflows and influence global as well as regional climates. Additionally, tropical landscapes are undergoing rapid changes due to both climate change and deforestation. The effects of these changes on water and biogeochemical processes, at a range of scales, are large but poorly understood. This Chapman Conference will examine current understanding of tropical ecohydrology and identify critical research needs in tropical systems.This Chapman Conference on "Emerging Issues in Tropical Ecohydrology" meeting will be held in Ceunca, Ecuador with three days of meetings and one day of field work. Themes will include (1) the influence of ecosystem degradation and recovery; (2) ecohydrological approaches and techniques for linking plant ecophysiological responses with watershed hydrology; (3) new concepts related to mechanistic assessment of the water balance across scales and across biomes (e.g., distributed modeling); (4) new techniques for measuring plant- and stream-water fluxes (e.g., stable isotopes, dendrochronology, sapflow, remote sensing, eddy covariance, distributed modeling); and (5) methods for building explicit linkages between ecophysiologists and ecohydrologists. The conference will result in a set of synthesis papers that lay out critical questions for ecohydrological research in the tropics and a cohesive strategy for addressing the most urgent ecohydrology research needs.
